Question

How is the shape of the stomach?
(a) As V
(b) As J
(c) As O
(d) None of the above

Answer 1

Hint: The shape of the stomach is similar to the letter that comes between the letters I and K. The exact position of the stomach in the alimentary canal is between the esophagus and the duodenum, which is the first part of the small intestine.

Complete answer:
The shape of the stomach is as J. It is a muscular hollow organ in the gastrointestinal tract located in the left part of the abdominal cavity, just inferior to the diaphragm of humans and many other animals including several invertebrates. The stomach is a roughly crescent-shaped enlargement of the gastrointestinal tract, located between the esophagus and the duodenum.

Additional Information:
- The stomach functions as a vital digestive organ in the digestive system. The stomach comes into action when chewing food enters the stomach through the esophagus.
- In the stomach, a chemical breakdown of food occurs through enzymes and hydrochloric acid.
- The stomach has two parts: fundus and pyloric. The dome- shaped fundus is located inferior to the diaphragm. Below the fundus is the main body of the stomach and the pyloric is funnel- shaped situated at the junction of the stomach and duodenum.

- The sphincters are bands of smooth muscles responsible for controlling the further movement of food.
- The pyloric sphincter is responsible for controlling the passage of partially digested food from the stomach into the duodenum where peristalsis occurs to move partially digested food through the rest of the intestines.
- Two sphincters keep the contents of the stomach contained; the lower esophageal sphincter that is found in the cardiac region, at the junction of the esophagus and stomach, and the pyloric sphincter is present at the junction of the stomach with the duodenum.
So, the correct answer is ‘J’.

Note:
- The stomach is located between the esophagus and the duodenum and it is also a roughly crescent-shaped enlargement of the gastrointestinal tract.
- The stomach has two parts: fundus and pyloric. The fundus is dome- shaped whereas the pyloric is funnel-shaped.
- A stomach can hold about one liter of food. The newborn human baby will only be able to retain about 30 milliliters of food in the stomach.
- The sphincters are bands of smooth muscles responsible for controlling the further movement of food.
